*Update*
Since I don't feel Scar is making any headway on this infection I scheduled him for another Vet visit. The Vet. decided to get an x-ray.
He said that everything looks good other than a little arthritis at one of his injury sites. I was very surprized that he didn't have any spinal damage, considering all the injuries he has.
Maybe I'm being over protective. I just don't want one of those sudden deaths, if I can avoid it.
I feel obligated to this little guy. I guess I need to take a deep breath and step back.
